Interesting results!

I'm "often".

I've started carrying one since I started doing more gardening and yardwork.

It's really useful and I like the way the object feels.

I have to remember to remove it from my pockets or bag when flying or going to see music. Otherwise, I keep it in my shoulder bag whenever I'm out of the house.
